- Thread Type: BSP (British Standard Pipe) threading for standard, reliable pipe fittings.
- Size: 3/8" x 19 TPI, offering a common BSP size for a wide range of applications.
- Design: Spiral Point geometry to push chips ahead and reduce risk of clogging during threading.

The spiral-point design enhances chip evacuation, helping maintain a smooth threading process even at higher speeds. The cobalt-infused HSS-E composition provides enduring performance under demanding shop conditions, reducing tool changes and boosting productivity. This tap is well-suited for plumbers, machinists, and DIY enthusiasts who require dependable BSP threading for reliable, long-lasting connections.
